Abstract
There is provided a radar device which is mounted on a moving object and configured to detect a target on the basis of reception signals acquired by receiving reflected waves from the target by receiving antennae. A transmitting unit has a transmission axis substantially parallel to a traveling direction of the moving object. The transmitting unit is configured to transmit transmission waves around the transmission axis as a center thereof. A determining unit is configured to determine upward axis misalignment or downward axis misalignment of the transmission axis, on the basis of the reception signals acquired by receiving the reflected waves of the transmission waves.
Claims11
A radar device which is mounted on a moving object and configured to detect a target on the basis of reception signals acquired by receiving reflected waves from the target by receiving antennae, the radar device comprising:
- a transmitting unit having a transmission axis substantially parallel to a traveling direction of the moving object and configured to transmit transmission waves around the transmission axis as a center thereof;
- and
- a determining unit configured to determine upward axis misalignment or downward axis misalignment of the transmission axis, on the basis of the reception signals acquired by receiving the reflected waves of the transmission waves.
A vertical axis-misalignment detecting method of a radar device which is mounted on a moving object and configured to detect a target on the basis of reception signals acquired by receiving reflected waves from the target by receiving antennae, the vertical axis-misalignment detecting method comprising:
- a transmitting process of transmitting transmission waves around a transmission axis as a center thereof, the transmission axis substantially parallel to a traveling direction of the moving object;
- and
- a determining process of determining upward axis misalignment or downward axis misalignment of the transmission axis, on the basis of the reception signals acquired by receiving the reflected waves of the transmission waves.
